IPC: F26B15/00
Filed: 1925-11-17
Abstract: 243,351. John, W. E., and Gill, G. Nov. 20, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Buildings and chambers; wheeled trucks, moving; humidity, controlling.-Fruit &c. is dried by being passed through a drying zone in which air is circulated in a helical path the rotary component of which repeatedly intersects the path of movement of the material and the longitudinal component is opposed to the direction of movement of the material. The material supported on shallow trays on trucks 5 is passed through a drying tunnel 3 having a series of air circulating circuits 12 - - 16, one for each truck. Each circuit includes a fan 25, steam radiator 26, tunnel section 17 and passages 18, 20 and 21 whereby the air heated in the radiator is passed over the material to be dried, the air in each succeeding compartment being circulated in an opposite sense. Fresh air after cooling the truck load in chamber 9 is admitted by door 38 and the moist air escapes through outlet 34 so that the material is first treated with moistened air and not dried too rapidly. Exhaust steam from the engine 40 is used in the radiators 26 from which the condensate is passed by pipes 42 to a hot well 28 to be returned to the boiler 41. Steam nozzles 45 are provided for moistening the atmosphere as desired.

Title: Improvements in or relating to the application of adhesive or like coatings to boot or shoe parts or the like
IPC: A43D25/18
Filed: 1931-10-21
Abstract: In a machine for applying adhesive to channels in the soles of boots or shoes, the adhesive is supplied to a rotary metallic coating roll 10, having surfaces at an angle to one another, by a transferring roll 16 having surfaces complementary to those of the roll 10, the roll 16 being supplied with adhesive by a roll 18 which dips into a trough of adhesive supplied from a reservoir 30 and is shaped <PICT:0391189/III/1> like the roll 10; a stripper or doctor roll (not shown) acting on the roll 18 is also provided.  To enable the amount of adhesive supplied to the roll 10 to be regulated, means for varying the distance between the rolls 16, 10 are provided; to this end, the roll 10 is carried on a shaft 20 supported in a bracket 22 which is movable vertically by means of a handscrew 32 and a lever 26 pivoted at 28.  To assist in pressing the flap of the channel against the roll 10, a tool 46 is provided.  The tool 46 is yieldingly supported at the end of a lever 44 pivoted at one end of an arm 42. The lever 44 is also adjustably connected to a rod 48 which is connected to one end of a lever 50; the other end of the lever 50 carries a roll 52 arranged to engage a cam face 58 on the driving pulley 59, whereby a vibratory motion is imparted to the tool 46. Normally, the roll 52 is held out of engagement with the cam face 58 by a spring (not shown) acting on a rod 55 in such a manner that a link 56 draws the roll 52 from the cam face, and also causes the tool 46 to be held out of working position; the rod 55 is connected to a foot pedal, by operating which the roll 52 is engaged with the cam face 58 and the tool 46 is moved into working position.  To enable the tool 46 to be lifted away from the roll 10, the arm 42 is pivoted at 41 to a bracket 40, the parts 42, 40 being connected when the tool 46 is in working position by a pin 43 passing through holes in both parts; to lift the tool 46, the pin 43 is removed and the arm 42 lifted about its pivot 41, and the pin 43 then replaced through the hole in the arm so as to rest on a lug 45 on the bracket 40.  An alternative form of the roll 10 is described in which the angularly disposed faces are cut by a number of intersecting grooves and are separated by a narrow groove or flat portion.  Two forms of flexible roll which may replace the roll 10 are also described; in one form the faces are at equal angles to the axis of the roll, while in the other from the faces are unequally arranged in relation to the roll axis, and one face is slightly concave; such flexible rolls may be made by moulding a mixture of treacle and glue around an irregular metallic core.  Specifications 26551/06 and 302,958, [both in Class 95, Paints &c.], are referred to.

Abstract: <PICT:0750254/III/1> In gas analysis apparatus for the detection or measurement of oxygen, according to Claim 1 of the parent Specification, the speed of response of the apparatus to oxygen is increased by forming the cathode of openwork structure and interposing a porous carrier for the electrolyte between the cathode and anode.  As shown, a glass tube 1 is surrounded by concentric tubes constituting the electrodes and the electrolyte carrier, and the assembly is mounted in a glass vessel formed in two parts 7, 8 connected at 9.  The cathode 4 is silver gauze held in position by silver wire 5; the carrier 3 is porous polyvinyl chloride and is soaked with aqueous caustic potash solution; the anode 2 is preferably lead foil, but may also be porous nickel impregnated with cadmium.  The gas to be tested is saturated with moisture and enters through tube 10, flows down tube 1, bubbles through a pool of liquid 18, e.g. the electrolyte, and then passes to annular space 14 into contact with the cathode, leaving the apparatus through tube 15. Electric leads 20, 21 are provided for the anode and cathode respectively.  Higher concentrations of oxygen are determined by using stainless steel instead of silver for the cathode.  An electrolysis apparatus for calibration purposes may be provided as described in the parent Specification and the liquid in this apparatus may be used to saturate the gas sample with moisture.  Two or more separate cathodes of different sensitivities may be used with a common anode to provide for different ranges of oxygen concentration.  The openwork cathode may be formed from wire mesh, perforated sheet, expanded metal, grids or wires.  Other materials suitable for the electrolyte carrier, apart from porous plastics, are filter paper, textile fabric, porous ceramic material, or asbestos. Reference is made to a cell comprising a gold cathode, sulphuric acid as the electrolyte, and a copper anode.  The apparatus may be used in connection with the production of oxygen-free nitrogen and argon and the filling of electric light bulbs and radio valves with inert gas.
